Pull request description:

  Removes the `-salvagewallet` startup option and adds a `salvage` command to the `bitcoin-wallet` tool. As such, `-salvagewallet` is removed. Additionally, the automatic salvage that is done if the wallet file fails to load is removed.

  Lastly the salvage code entirely is moved out entirely into `bitcoin-wallet` from `walletdb.{cpp/h}` and `db.{cpp/h}`.

ACKs for top commit:
  jonatack:
    ACK 84ae0578b6 feedback taken, and compared to my previous review, the bitcoin-wallet salvage command now seems to run and it exits without raising. The new test passes at both 9454105 and 84ae057 so as a sanity check I'd agree there is room for improvement, if possible.
  MarcoFalke:
    re-ACK 84ae0578b6 🏉
  Empact:
    Code Review ACK 84ae0578b6
  ryanofsky:
    Code review ACK 84ae0578b6. Lot of small changes since previous review: added verify step before salvage, added basic test in new commit, removed unused scanstate variable and warnings parameter, tweaked various comments and strings, moved fsuccess variable declaration
  meshcollider:
    Concept / light code review ACK 84ae0578b6
